Like the Senate bill, which has won unexpected support from Amazon.com, the House legislation also has a “small seller exception,” exempting out-of-state vendors that have annual gross receipts less than $100,000 in-state or $1 million nationally.

The bill calls for state to enact a “simplified” system for revenue collection, with a single statewide rate, as well as a single revenue authority.

“The intent of this legislation is not to be instructive, but instead to close a long-standing loophole that puts America’s brick and mortar businesses at a competitive disadvantage,” Womack said in a statement. “The nation’s retailers—both big and small—deserve to compete on a level playing field.”

Laws requiring Internet companies collect sales tax are now on the books in Arkansas, Connecticut, Illinois, California, Rhode Island, New York, and North Carolina. Laws requiring companies to notify consumers they owe taxes are in place in South Carolina and Colorado.
